Markedly more performance with new milling cutter

For its newly developed Fourworx indexable insert milling cutter, Pokolm promises a variety of interesting properties and a completely redesigned overall geometry. As a result, even the smallest tool diameter of 16 mm now boasts three inserts.

With this genuine industry innovation, as the exhibitors describe it, cutting depths up to ap 0.75 mm and feed rates up to fz 1,2 mm/tooth can be achieved. Despite the small tool diameter, the original geometry is claimed to ensure maximum stability in use, with similar attributes also applying to the inserts. Even with the compact dimensions, a clearly visible and innovative reinforcing collar around the screw seat together with a negative insert seat provides for a significantly extended service life. At the same time, chamfered outer edges protect the inserts against spalling around the circumference and a 3D chip pocket guarantees optimum chip removal paired with maximum cutting performance. The corner radius of 1 mm stands for extreme stability at the outer tool diameter, even at high feed rates. As the manufacturers explain, the precision inserts have four cutting edges. In four different grade and coating combinations and with two chip-breaker grooves, they reportedly allow the machining of a broad range of materials and are optimally suitable for the machining of steel, cast iron and SAH materials such as titanium and Inconel. Even on less powerful machines, the new milling cutters are said to offer top performance, with the new milling system also proving its capabilities with fragile workpieces and in deep cavities, both in wet and dry machining. The milling cutter is available in diameters of 16 to 42 mm as end mills, threaded-shank mills and with the patented Duoplug system for optimized concentricity and maximum rigidity.
